[ZIGBEE] usage of zb_zcl_ias_zone_set_status function

[_maibi]

Hi, I have developed custom board on nRF52840 based on Thread and Zigbee SDK 14.1.0.

I wants to use zb_zcl_ias_zone_set_status function to send a report of the changed zone status.

 

/**
   @brief Use this function to change IAS Zone status. This function
   will set new value of ZoneStatus and will send Zone status change
   notification.
   @note If another API (ZB_ZCL_SET_ATTRIBUTE()) is used for modifying
   ZoneStatus, notification will NOT be send. This is limitation of
   the current implementation.
   @param ep - local endpoint number
   @param new_val - new value for ZoneStatus
   @param delay - delay in quater seconds (actual only for HA ZCL
   version, is ignored for pure ZCL implementation)
   @param buf_param - reference to a buffer that will be used for
   sending notification. If buffer reference is not specified,
   notification will NOT be sent
   @return Returns ZB_TRUE if notification is scheduled for send,
   ZB_FALSE otherwise
   @note Notifiacation send result is reported to user App using
   callback that is registered with zb_zcl_ias_zone_registrer_cb()
*/
zb_bool_t zb_zcl_ias_zone_set_status(
  zb_uint8_t ep,
  zb_uint16_t new_val,
  zb_uint16_t delay,
  zb_uint8_t buf_param);

 

I tried this way.

zb_bool_t ret;
zb_uint16_t ias_zone_state = ZB_ZCL_MY_IAS_ZONE_ZONE_STATUS_LOW_BATTERY;


ZB_ZCL_CLUSTER_ID_IAS_ZONE_SERVER_ROLE_INIT();

ret = zb_zcl_ias_zone_set_status(DOOR_LOCK_ENDPOINT,
                        ias_zone_state,
                        0,
                        0);
DEBUG_PRINTF("IAS STATUS RET: %d\r\n", ret);

IAS STATUS RET: 0

How I get "buf_param" to pass zb_zcl_ias_zone_set_status function?

And, How can I take a goal?

Hi,

The buf_param argument references to the buffer that will be used for sending notification. If buffer reference is not specified, notification will not be sent.

You should also used on of the valid values for ZoneStatus: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_tz_v3.2.0%2Fgroup___z_b___z_c_l___i_a_s___z_o_n_e.html&anchor=ga1ac890943ce2869a4fe2f403db97357f

The function should return ZB_TRUE (= 1)  if notification is scheduled for send.

Best regards,

Marjeris
